You read the first one as " yahari" and the second one as "yappari". The meaning is the same, however "yappari" is rather a colloquial, spoken word. They're both usually written in hiragana, not kanji.
ここはやはりきれいです。(Koko wa yahari kirei desu.) - "After all, it is beautiful here."
彼女は頭がいいけどやっぱりうざいだ。(Kanojo wa atama ga ii kedo yappari uzai da.) - "She's smart but still annoying, just as I was thinking."
